Here are three effective methods to efficiently control font sizing in your CSS:
Method One:
1) Utilize the rem scaling measurement
Avoid using px, opt for the rem metric instead. The rem, or Root em, framework begins from a base value, set by the :root element, which is essential for the next step.
2) Employ @media queries to regulate the root-em size
After establishing the initial setting, customize it further using media queries to control the root-em (rem) value within each query.
Example:
:root {
font-size: 16px; /* sets 1rem */
}
.footer-link{
font-size: 0.9rem; /* 16 x 0.9 */
width: 5rem;
padding-bottom: calc(100% - 5rem);
}
@media screen and (max-width:500px){
:root {
font-size: 14px;
}
}
NOTE: Adjusting font-size: within html{ ... } might potentially conflict with browser settings (not confirmed by me).
Method Two:
Building upon Method One, incorporate CSS Variables for enhanced adaptability.
Example:
:root {
--widthValue: 80%;
font-size: 16px; /* still necessary to establish 1rem */
}
.footer-link{
font-size: 1rem;
width: var(--widthValue);
padding-bottom: calc(100% - var(--widthValue));
}
@media screen and (max-width:500px){
:root {
font-size: 15px;
--widthValue: 76%;
}
}
CSS Variables allow fine-tuned adjustments not easily achievable with rem values. For more information, check out this resource.
Method Three:
Initially, I had a third method in mind, but the first two should sufficiently address your requirements.
I know about media queries, but I'm concerned about rewriting every section of code and adjusting sizes individually.
While modifications to your core CSS are inevitable, transitioning from static code to variable-based systems enables greater flexibility and ease of management.
The solution proposed emphasizes Don't Repeat Yourself principles--by altering a single value in a @media query, cascading style updates can be effortlessly propagated throughout your stylesheets.
